Abstract The strength calculation is very important in the design of the tank. Significant efforts have been made to solve this task and have led to standardized procedures, recommendations and standards for tank design. Within the existing standards, the designers are able to define mainly the geometry of the tank and technical conditions of the structure. When it is necessary to check the stability of the shell or the complete tank, they resort to analytical methods with the use of classical patterns from general theory of shells. As is well known, the application of general shell theory, even in the simplest of cases, leads to very complex calculations. When using membrane theory in the calculation, it is shown that satisfactory results are obtained only for parts of the shell far enough from ends, but it cannot satisfy all the conditions on the contour and the area of supports. Keywords: tank, optimisation, stress, finite element method (FEM) |
